TRUNNION-BEARIN GUARD.

Application filed October 31, 1927. Serial No. 230,036.

This invention relates to iii'iproveinents in trunnion bearing guards, adapted to be used in metal pouring devices.

Heretofore, in metal pouring devices, the bearings, at the point where the trunnions of the container holder enter them, have been entirely unprotected. .As a result, molten metal which has been spilled over the sides of the container has become lodged around the bearings, and hasthere hardened or corroded, thereby preventing thetrunnions from turning within the bearings.V

It is one of the objects of the present invention to provide a guard for the trunnion bearings which will obviate the aforementioned objection.

It is a more specific object of this invention to provide a semi-circular protecting flange on the inner end ofy each bearing, and a groove below the flange extending around the circumference of each of the trunnioiis.

A further object of the invention is to provide a trunnion bearing guard which is simple in construction and operation, and is well adapted for the purpose described.l

With the above and other objects in view, the invention consists of the improved trunnion bearing guard and its parts and combinations as set forth in the claims and all equivalents thereof.

In the accompanying drawing in which the saine reference characters indicate the sanie parts in all of the views:

Fig. 1 is a front elevation of a portion of a metal pouring device, showing the trunnion bearing guards in combination therewith;

Fig. 2 is a sectional view of one of the bearings and trunnion showing the bearing guard; and

F ig. 3 is a section taken on the line 3.-3 of Fig. 2.

Referring to the drawing, the numeral 5 designates a bail kon each end of which is a trunnion bearing 6. The trunnion bearings are provided with upwardly extending brackets y7 by whichthe bearings are secured to the bail arms by bolts and nuts 8. Connected to the bail by brackets 9 is the container tilting mechanism which comprises a control wheel 11 rigidly secured to a rod 12 which has rigidly secured thereto a worin wheel 13 for rotating the gear wheel v14: which in turn rotates the trunnion 15. The

turning of the trunnion causes the tilting of the container 16 which is positioned within the container holder 17.

One of the novel features of this invenltion resides in the construction of the trunnion bearings 6. These bearings are formed on their inner ends with semi-circular flanges 18. lVhile semi-circular flanges are the preferred type, it is not 2l secured tothe bearings by bolts 22 and nuts 23. y

The trunnions are provided with circumferential flanges 24 which are adjacent the inner ends of the bearings 6. Adjacent to these flanges, the trunnions have'circumferential grooves 25 formed therearound.k These grooves are a further novel feature of the invention. As they are located directly below the 'edges of the semicircular flanges 18, any molten metal which splashes on and drips ofl" of the flanges will'be received by the grooves 25 and thereby kept away from Contact with the points where the flanges 24- meet the bearings 6. Furthermore, when the trunnions are turned, the molten metal will become dislodged from the grooves and fall to the floor.

From the foregoing description, it may be seen that the improved trunnion bearing guard is of very simple construction and is well adapted for the purpose described.

What I claim as my invention is:

l. In a bearing, a shaft mounted in sait bearing and projecting therefrom, and a protecting flange on the bearing overhanging and extending partly around a portion of said shaft which projects from the bearing, all parts'of said flange being spaced from said shaft, and the said shaft being exposed for a distance inwardly from the end of the flange.

2. In a bearing, a shaft mounted in said bearing and projecting therefrom and having a groove on a portion of said shaft which projects from'the bearing, and a protecting flange on the hearing above the said groove.

sol

3. In a bearing, a shaft mounted in said bearing and projecting therefrom, a circumferential flange on said shaft adjacent the bearing, said shaft having a groove adjacent the circumferential flange, and a protecting flange on the bearing above the said groove.

4;. In a bearing, a shaft mounted in said bearing and projecting therefrom, a circumferential flange on said shaft adjacent the bearing, said shaft having a groove adjacent the circumferential flange, and a protecting flange on the bearingl above the-said groove and extending partly around the grooved portion of the shaft.

5. The combination with a pouring device having.v a bail, bearings on the ends of' said bail, trunnions mounted in said bearings and projectingtherefrom, a container' carried by saidV trunnions and tiltably mounted' Within the bail, and protecting flanges on said' bearings overhanging portions of said trunnions Which project from the bearings, all portions of the flanges being spaced from the trunnions, and the trunnions being exposed for a` distance inwardly from the ends of the flanges.

6. The combination with a pouring device having a bailbearings on the ends of said bail, trunnions mounted in said bearings and projecting therefrom, a container carriedv by said trunnions and1 tiltably mounted Within the bail, and semi-circular protecting flanges on said bearings overhanging portions of said trunnions which project from the bearings, all portions of the flanges being spaced if rom the trunnions, and the trunnions being exposed fro a distance inwardly from the ends of the flanges.

7. The combination With a pouring device having al bail, bearings on the ends of said bail, trunnions mounted in said bearin gs and projecting therefrom, a container carried by saidtrunnions and tiltably mounted Within the bail, said trunnions having grooves, and protecting flanges on said bearings above the said grooves. l

8, rlhe combination with a pouring device having a bail, bearings on the ends of said bail, trunnions mounted in said bearings and projecting therefrom, a rcontainer' carried by, said trunnions and tilt'ably mounted Within the bail', a circumferential flange on each of said trunnions adjacent the bearings and between the bearings and the container, each trnnnion adjacent the said flanges having Va groove, and a protectingflange on each bear ing above the adjacent groove.

9. The combination With a pouring device having a bail, bearings on the ends of said bail, trunnions mounted in said' bearings and projecting therefrom, a container carried by said trunnions and tiltably mounted within the bail, a circumferential flange on each of said trunnions adjacent the bearings, each trunnion adjacent the said flanges having a groove, and a semi-(circular protecting flange on each bearing above the adjacent groove.

In testimony whereof, I affix my signature.
